Just for fun...
Let's assume the starting 5 is going to be Kyrie, Hayward, Tatum, Brown and Horford and they're healthy all year. Where will their scoring averages fall for the whole regular season? I think overall FG% is going to be up because everyone is a scoring threat from all over the floor.
I say:
Kyrie Irving: 23ppg, 50% fg, 42% 3pt
Jayson Tatum: 20ppg, 50% fg, 43% 3pt
Gordon Hayward: 19ppg, 48% fg, 40% 3pt
Jaylen Brown: 16ppg, 48% fg, 40% 3pt
Al Horford: 10ppg, 52% fg, 42% 3pt
